The BZX84C12 TR is one of a series of Zener diodes that have superior reliability and low-leakage capability. This device is specifically designed for use in applications where top-side mounted components are required. It is also the highest power rating available in this series of diodes.

The BZX84C12 TR is a single diode with a voltage rating of 12 volts and a reverse leakage current of 5 microamps. It features low power consumption, low input saturation voltage and high reliability. The device has a do-35 package with two pin configurations, a SR and SR2.

The BZX84C12 TR is an ideal device for applications that require low-voltage operation with low leakage current. It is suitable for applications in:

• Security systems
• Computer control circuits
• Battery-powered equipment
• Telecommunication equipment
• Automotive applications
• Industrial control circuits

The device works on the principle of reverse-biased avalanche breakdown. With a reverse voltage above the breakdown voltage, a current flows through the Zener diode forming a Zener junction. This results in either a small drop in the current or a large change in the voltage across the diode. The breakdown voltage of this device is 12V and it is typically used for voltage regulation and protection against overvoltages.

The Zener diode has two limiting characteristics, the Zener voltage and the Zener resistance. The Zener voltage is the voltage at which the diode breaks down and the Zener resistance is the resistance of the diode in the reverse-biased avalanche breakdown region. This device has a low Zener resistance of 0.2Ω which ensures a low leakage current in this region.

The BZX84C12 TR is a device that is both reliable and cost-effective for a variety of hazardous environment or high reliability applications. It is easy to use and the high-temperature self-bias version is ideal for reliable operation in high temperatures. The stamped-steel construction makes it very reliable in difficult environments, adding to its versatility.
